For this yakuman, all [[kazehai]] (wind tiles) and [[sangenpai]] (dragon tiles) can be used. Given the nature of [[jihai]] (honor tiles), the different types cannot be mixed to form [[mentsu|tile groups]].  Therefore, they must be collected in the form of [[Mentsu#Koutsu|koutsu]] (triplets).  This yakuman is only reasonably achievable, when in possession of at least multiple [[toitsu]] (pairs) of the honor tiles.  Otherwise, players may have to resort towards yaku, like [[yakuhai]] or [[honitsu]] for attaining [[tenpai]].

A specific variant to tsuuiisou is possible and can be considered as a separate yakuman, '''daichiisei''' {{kana|大七星}}.  It is a variant of [[chiitoitsu]] (seven pairs). This variant uses two of the each honour tiles and is sometimes called a "Dai Chii Sei" or Big Seven Stars. There are exactly seven types of honor tiles, which makes this difficult pattern possible.  As a consequence, this variation remains as a closed only hand. This is optionally worth [[optional yaku|double yakuman]].
In addition to triplets, tsuuiisou can be achieved in the form of [[chiitoitsu]]. This may be considered as a [[Optional yaku|separate yakuman]], '''daichiishin''' {{kana|大七星}}, meaning "Big Seven Stars". There are exactly seven types of honor tile, and you cannot call pon to complete the hand, so this is much harder than regular tsuiisou. This is [[optional yaku|optionally]] worth [[Multiple yakuman|double yakuman]].

Tsuuiisou 「字一色」 is a yakuman in which the hand consists entirely of honor tiles.

Tile pattern

Agari: or

Development

For this yakuman, all kazehai (wind tiles) and sangenpai (dragon tiles) can be used. This gives seven tiles to choose from.

Honor tiles can only be formed as triplets or pairs. Therefore, this yakuman is only reasonable when in possession of multiple toitsu (pairs) of the honor tiles. Otherwise, you can go for yaku like yakuhai and honitsu. Regarding tile discards, any tile that is not an honor tile is deemed irrelevant for the yakuman, including dora tiles. More often than not, players will call pon in order to claim and complete honor tile groups, until tenpai and eventually winning the hand (assuming to be the case).

Daichiishin

Agari:

In addition to triplets, tsuuiisou can be achieved in the form of chiitoitsu. This may be considered as a separate yakuman, daichiishin 「大七星」, meaning "Big Seven Stars". There are exactly seven types of honor tile, and you cannot call pon to complete the hand, so this is much harder than regular tsuiisou. This is optionally worth double yakuman.
